|
 | A connector splicing optical fibers wherein a glass sleeve, having a precision cut bore formed therein, is provided with funnel-shaped access openings at each end thereof for receiving the ends of the glass fibers to be spliced. In one embodiment, a permanent splice is made by applying a bonding agent and sealant to the funnel-shaped openings, and in another embodiment, a retainer ring is employed to thereby provide a disconnectable ... |

|
| NG INFLUENCE OF THE GRAIN SIZE OF BARIUM STRONTIUM TITANATE ON THE PERMITTIVITY RATIO, THE VARIATION OF PERMITTIVITY WITH SUPERIMPOSED DC BIAS, IS PRESENTED AS A FUNCTION OF TEMPERATURE. A 10-fold decrease in permittivity with 80 v/mil dc bias was obtained at the Curie temperature of a ceramic with coarse grains. The mechanisms responsible for the field dependent change in permittivity, namely a field induced paraelectric to ferroelectric transition and ... |

|
| A new process was devised for producing barrier-layer dielectrics from high purity barium titanate. The process developed permits the formation of a dielectric with high capacitance per unit volume by a one-fire treatment with the use of controlled atmosphere in place of three separate firings presently required. A barrier-layer dielectric was produced that had a capacitance of 3400 picofarads in a bulk volume of 0.0062 cu in and dissipation factor ... |
